[0002] Medical steam sterilizer is a device used to sterilize medical devices and equipment. It mainly uses high temperature and high pressure steam to kill bacteria, viruses, fungi and other microorganisms to ensure the thorough sterilization of medical devices. Medical steam sterilizers usually use saturated steam, which is a state of saturated water vapor at high temperature. The high temperature and high pressure of steam can destroy the cell structure and metabolic function of microorganisms, thereby effectively killing them.

[0003] Steam sterilizers can be used to sterilize various medical devices and equipment, including surgical instruments, syringes, needles, oral instruments, laboratory instruments, etc. Medical steam sterilizers usually have the advantages of high temperature and pressure, high stability, high reliability, rapid sterilization, and high safety. Medical steam sterilizers are widely used in medical institutions, laboratories, and other health care places to ensure the thorough sterilization of medical devices and equipment, thereby reducing the risk of infection and protecting the health and safety of patients and medical staff.

[0004] When using a steam sterilizer, the display of the steam sterilizer will show the temperature and pressure data detected by the internal sensor. After long-term use, the internal sensor elements of the steam sterilizer are prone to aging, especially in a high temperature and high pressure environment, which will accelerate the aging of the sensor. The detection data of the aged sensor will produce deviations, affecting the use of the steam sterilizer, and when the pressure in the steam sterilizer is too high, the use of the steam sterilizer is prone to danger. In order to detect the aging degree of the internal sensor of the steam sterilizer and calibrate the sensor detection data, a medical steam sterilizer temperature and pressure parameter calibration instrument is now provided.

Therefore, a medical steam sterilizer temperature and pressure parameter calibration instrument is proposed.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figure 1-5 This embodiment provides a medical steam sterilizer temperature and pressure parameter calibration instrument, including a host 1.

[0023] Specifically, the host 1 refers to the boiler pressure and temperature detector of model SIN-R5000C, and one end of the host 1 is connected to the temperature sensor 11 and the pressure sensor 12. Among them, the temperature sensor 11 refers to the thermocouple probe of model WRNT-10, which can detect temperature. The pressure sensor 12 refers to the pressure transmitter of model SIN-P300, which can detect air pressure. The temperature sensor 11 and the pressure sensor 12 can transmit the detected temperature and pressure data to the host 1 for display.

[0024] like Figure 1 As shown, the other ends of the temperature sensor 11 and the pressure sensor 12 are threadedly connected to the detection chamber 2. Figure 2 As shown, the detection end of the temperature sensor 11 is plugged into the detection chamber 2, and the detection head of the pressure sensor 12 is connected to the detection chamber 2, so that the temperature sensor 11 and the pressure sensor 12 can detect the temperature and pressure in the detection chamber 2.

[0025] like Figure 1 and Figure 2 As shown, the two ends of the detection chamber 2 are respectively connected with an air inlet pipe 21 and an exhaust pipe 22, the air inlet pipe 21 is used to inject steam into the detection chamber 2, and the exhaust pipe 22 is used to exhaust steam. The exhaust pipe 22 is installed with an air valve 221, which is a copper ball valve with reference model TK-5136 and is used to control the opening and closing of the exhaust pipe 22.

[0026] In order to facilitate the detection of temperature and pressure parameters in the medical steam sterilizer, the air inlet pipe 21 of the detection chamber 2 is provided with a connecting mechanism 3 .

[0027] Specifically, the connection mechanism 3 includes a hose 31, a connecting pipe 32 and a tightening pipe 33, wherein the two ends of the hose 31 are respectively connected to the air intake pipe 21 and the connecting pipe 32, so that the air intake pipe 21, the connecting pipe 32 and the interior of the detection chamber 2 are interconnected. The tightening pipe 33 is threadedly sleeved on the outer wall of the connecting pipe 32.

[0028] The hose 31 and the connecting tube 32 form a sleeve. When in use, the sleeve is sleeved on the outer wall of the air outlet pipe of the medical steam sterilizer (when the sterilizer is turned on, the air outlet pipe needs to be opened to release the pressure so that the air pressure inside and outside the sterilizer is consistent), and the tightening tube 33 is rotated to move the tightening tube 33 toward the hose 31. Figure 4 As shown, one end of the outer wall of the hose 31 and one end of the inner wall of the tightening tube 33 are provided with inclined surfaces that fit each other. The hose 31 is made of high-temperature resistant rubber material. When the tightening tube 33 continues to move, the tightening tube 33 applies an extrusion force to the hose 31, and the tightening tube 33 squeezes the hose 31, causing the hose 31 to deform. After the tightening tube 33 moves and is connected to the outer wall of the hose 31, the hose 31 is tightly sealed and fitted with the air outlet pipe of the steam sterilizer, thereby completing the sealed connection between the sleeve and the air outlet pipe.

[0029] When the parameters displayed by the medical steam sterilizer need to be calibrated, a known and accurate temperature sensor 11 and pressure sensor 12 are selected, the temperature sensor 11 and pressure sensor 12 are connected to the main unit 1 and the detection chamber 2, the sleeve composed of the rubber hose 31 and the connecting pipe 32 is sleeved on the outer wall of the air outlet pipe of the medical steam sterilizer, and the tightening tube 33 is tightened to squeeze the rubber hose 31 so that the sleeve is sealed and connected with the air outlet pipe. The medical steam sterilizer is started to perform sterilization operation, the air valve 221 is controlled to close the exhaust pipe 22, and the medical steam sterilizer is controlled to open the air outlet pipe, so that the steam in the medical steam sterilizer enters the detection chamber 2 through the air outlet pipe and the sleeve, so that the temperature and pressure inside the detection chamber 2 are the same as those inside the medical steam sterilizer.

[0030] At this time, the temperature sensor 11 and the pressure sensor 12 work, and transmit the temperature and pressure parameters in the detection chamber 2 to the host 1, which are displayed on the display screen of the host 1. The sensor inside the medical steam sterilizer also transmits the detected data to the display screen of the medical steam sterilizer for display, and compares the temperature and pressure parameters displayed on the display screens of the host 1 and the medical steam sterilizer. When the two sets of parameters are different, the parameter calibration is completed by modifying the parameter data of the medical steam sterilizer or by replacing the internal sensor of the medical steam sterilizer.

[0031] After the calibration is completed, when the medical steam sterilizer needs to be turned on, the air valve 221 can be used to open the exhaust pipe 22 to complete the steam exhaust operation, so that the medical steam sterilizer is consistent with the external pressure.

[0032] Since the hose 31 is made of rubber and can be deformed, when the hose 31 is sleeved on the outer wall of the outlet pipe of the medical steam sterilizer, the outer wall of the outlet pipe will form a reverse force with the inner wall of the hose 31, which will cause the hose 31 to be stretched and deformed. In order to prevent the stretching of the hose 31 from accelerating the aging of the hose 31 and reducing the service life of the hose 31, an elastic bar 311 is fixedly connected between the connecting pipe 32 and the air inlet pipe 21.

[0033] Specifically, the spring bar 311 is inserted into the hose 31. The spring bar 311 is set as a metal bar. When the hose 31 is deformed under pressure, the spring bar 311 can bend along with the deformation parameters of the hose 31. At the same time, the spring bar 311 limits the distance between the connecting pipe 32 and the air intake pipe 21, thereby preventing the hose 31 from stretching.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
